Seismic pile–slope stability analysis and the formation mechanism of soil arching have not been well studied. This study used a threedimensional(3D) finite difference to determine soil and pile parameter changes in the static and seismic stability of the pile–slope caused by the interaction between stabilizing piles. Pile–slope stability analysis was performed to determine the optimal design of piles along a slope and the corresponding failure mode involving the formation of soil arching around two adjacent piles. The Factor of Safety(FS) of the slope was evaluated using the shear strength reduction method for static and seismic analyses. The results of the analysis show that suitable pile spacing(S) and a suitable pile diameter(D) in the middle of a slope result in the maximum FS for the pile–slope system and the formation of soil arching around two adjacent piles. FS of the pile–slope increased negligibly in the seismic analysis of piles located at the slope crest and toe. An optimized pile diameter and installation location afforded the maximum FS for the slope that corresponded to a specified slope failure mode for different pile locations. A pile spacing S ≤ 2.5D for piles installed in the middle of the slope is suggested for increasing the static and seismic pile–slope stability.

With the ever-growing storage density, high-speed, and low-cost data access, flash memory has inevitably become popular. Multi-level cell(MLC) NAND flash memory, which can well balance the data density and memory stability, has occupied the largest market share of flash memory. With the aggressive memory scaling, however, the reliability decays sharply owing to multiple interferences. Therefore, the control system should be embedded with a suitable error correction code(ECC) to guarantee the data integrity and accuracy. We proposed the pre-check scheme which is a multi-strategy polar code scheme to strike a balance between reasonable frame error rate(FER) and decoding latency. Three decoders namely binaryinput, quantized-soft, and pure-soft decoders are embedded in this scheme. Since the calculation of soft loglikelihood ratio(LLR) inputs needs multiple sensing operations and optional quantization boundaries, a 2-bit quantized hard-decision decoder is proposed to outperform the hard-decoded LDPC bit-flipping decoder with fewer sensing operations. We notice that polar codes have much lower computational complexity compared with LDPC codes. The stepwise maximum mutual information(SMMI) scheme is also proposed to obtain overlapped boundaries without exhausting search. The mapping scheme using Gray code is employed and proved to achieve better raw error performance compared with other alternatives. Hardware architectures are also given in this paper.

Background Previous studies have noted that there is a high utilization rate of traditional Chinese medicine （TCM） services in Taiwan, China and in western countries, but few studies investigated factors associated with the utilization of TCM in Taiwan. This study analyzes the utilization rate and the factors associated with the utilization of TCM in Taiwan. Methods Data for this study were from the 2002 HPKAP Survey that conducted the face-to-face questionnaire interviews of people aged 15 years and over from October 2002 to March 2003 in Taiwan. This study analyzed the utilization of TCM outpatient services, including admission to the hospital and clinic visits. Results A total of 26 755 participants completed the survey in the six-month period. The data revealed that 10.4% of participants had utilized TCM services in the past one month while 4.2% of participants utilized TCM only （without using Western medicine outpatient services （WM） or Folk therapy （FT））. The average visits of TCM services per patient was higher among people who had utilized TCM and FT services （2.68 visits） than among those who had utilized WM and FT services （2.15 visits） or TCM services alone （2.15 visits） during the previous one month. Younger people （odds ratio OR = 1.78, 95%CI= 1.47-2.16）, women （compared with men）, and people with higher education levels （OR = 1.58, 95%CI= 1.25-1.98） were more likely to visit TCM than compared groups. People with self-reported poor health status （OR = 2.07, 95%CI= 1.76-2.44） and people who exercise regularly （OR = 1.17, 95%CI= 1.07-1.27） had higher ORs to visit TCM service than comparison group. Conclusions There is a high utilization of TCM in Taiwan. Further studies are needed to investigate the related factors and determinants between the utilization of TCM and the utilization of FT in Taiwan.

Helicobacter pylori(***)infection is highly associated with the occurrence of gastrointestinal diseases,including gastric inflammation,peptic ulcer,gastric cancer,and gastric mucosa-associated lymphoid-tissue *** alternative therapies,including phytomedicines and probiotics,have been used to improve eradication,current treatment still relies on a combination of antimicrobial agents,such as amoxicillin,clarithromycin,metronidazole,and levofloxacin,and antisecretory agents,such as proton pump inhibitors(PPIs).A standard triple therapy consisting of a PPI and two antibiotics(clarithromycin and amoxicillin/metronidazole)is widely used as the first-line regimen for treatment of infection,but the increased resistance of *** to clarithromycin and metronidazole has significantly reduced the eradication rate using this therapy and bismuth-containing therapy or 10-d sequential therapy has therefore been proposed to replace standard triple ***,levofloxacin-based triple therapy can be used as rescue therapy for *** infection after failure of first-line *** increase in resistance to antibiotics,including levofloxacin,may limit the applicability of such ***,since resistance of *** to amoxicillin is generally low,an optimized high dose dual therapy consisting of a PPI and amoxicillin can be an effective first-line or rescue *** addition,the concomitant use of alternative medicine has the potential to provide additive or synergistic effects against *** infection,though its efficacy needs to be verified in clinical studies.

Amis is the largest aboriginal population in Taiwan. The previous dermatoglyphic studies of the Amis only reported limited data. In this study, we collected and analyzed the dermatoglyphs of 200 Amis in-dividuals, and we reported a wide range of dermatoglyphic variables including total finger ridge count, a-b ridge count, atd angle, axial triradius percent distance, and frequencies of fingerprint pattern, pal-mar thenar pattern, palmar interdigital pattern, and simian line. This study is the first comprehensive dermatoglyphic research of Amis since 1960s, and its dermatoglyphic data will be useful for future re-search in anthropology, genetics and medicine.
